Write \([\mathrm{A}][\mathrm{X}]=[\mathrm{B}]\), if possible, for the matrices given in Problems 17-18.

\([\mathrm{A}]=\left[\begin{array}{rrr}1 & 2 & 4 \\ -3 & 2 & 1 \\ 2 & 0 & 1\end{array}\right],[\mathrm{X}]=\left[\begin{array}{l}x \\ y \\ z\end{array}\right]\), and \([\mathrm{B}]=\left[\begin{array}{r}13 \\ 11 \\ 0\end{array}\right]\).
